|February 1, 1990
Summary
This study reports 11 pyogenic psoas abscess cases, primarily caused by Staphylococcus aureus. Ultrasound-guided drainage and antibiotics are effective, with antibiotics alone showing promise for early-stage abscesses.
Area of Science:
- Medical Imaging
- Infectious Diseases
- Surgical Procedures
Background:
- Pyogenic psoas abscesses are uncommon infections requiring prompt diagnosis and treatment.
- Staphylococcus aureus is a common causative pathogen in these infections.
Purpose of the Study:
- To report on 11 cases of pyogenic psoas abscesses.
- To evaluate the utility of ultrasonography (US) in diagnosis and management.
- To assess the effectiveness of different therapeutic approaches.
Main Methods:
- Retrospective case series of 11 patients with pyogenic psoas abscesses.
- Diagnosis and follow-up primarily utilized ultrasonography.
- Treatment modalities included percutaneous drainage with antibiotics and antibiotic therapy alone.
Main Results:
- Staphylococcus aureus was identified in all cases.
- Ultrasonography proved valuable for diagnosis and monitoring abscess evolution.
- Percutaneous drainage under US guidance combined with antibiotics was effective.
- Antibiotic therapy alone was effective for presuppurative and uncomplicated primary abscesses.
Conclusions:
- Ultrasonography is a key tool for diagnosing and managing pyogenic psoas abscesses.
- Combined percutaneous drainage and antibiotics offer an effective treatment.
- Antibiotic therapy alone may suffice for early or uncomplicated cases, avoiding invasive procedures.
